This test measures the ratio of arachidonic acid (AA) to eicosapentaenoic acid (EPA) in plasma. This ratio of the principle omega-3 and omega-6 fatty acids is a measure of the body’s eicosanoid balance. Balancing these eicosanoids in the body is an excellent way
for managing heart disease and other chronic and inflammatory processes.
Even though cellular or chronic inflammation is silent (absent of pain signals), it can be measured with a number of medical tests.
The AA/EPA Ratio is one of the most common tests for cellular inflammation.
The two other common tests are:
- hs-C-reactive protein (hs-CRP)
- Nuclear factor kappa-B (NF-kB)
EPA (n3) and AA (n6) both compete for use of the delta-5- desaturase enzyme to be synthesized. Increased dietary intake of animal fats alters fatty acid metabolism in favor of inflammation. There are many chronic diseases associated with elevations of this ratio including cardiovascular disease, mood disorders, and cancer.207-212 Increasing dietary intake of fish oils, or omega-3 fatty acid containing foods such as flax, chia, oily fish, or walnuts, can shift delta-5-desaturase activity toward the metabolism of the more beneficial n-3 metabolites. Decreasing intake of animal fats is also recommended.
